USING THE PROJECTOR
This section describes how to use and make adjustments to the 
projector. It also provides a reference to the keypad and remote 
buttons and the options available from the on-screen menus.
Basic Image Adjustment
1
If the image doesn’t display completely, zoom the image 
(page 27), adjust the height of the projector (page 28), choose a 
different screen aspect (page 35) or choose a different resize 
option (page 42). Be sure the projector lens is at a 90 degree 
angle to the screen.
2
If the image is out of focus, rotate the focus ring (page 27).
3
If the image is not square, adjust the keystone (page 31).
4
If the colors don’t look right, adjust the brightness, contrast, 
tint, color, or sharpness (page 34) or the color space or gain 
(page 44).
Adjusting the Projector
To focus the image, rotate the focus ring (Figure 20) until the 
image is clear. To zoom the image, rotate the zoom ring. This 
adjusts the image size. You can also zoom in on part of the image, 
see page 32.
NOTE: To obtain the best overall 
focus quality, open the menu and 
focus on the text. This will ensure 
that the best overall image quality 
is achieved.
